Crowdsourcing becomes a market of steadily growing importance on which both academia and industry, rely increasingly heavily. However, this market appears to be inherently infested with a significant share of malicious workers who try to maximise their profits through cheating or sloppiness. This serves to undermine the very merits crowdsourcing has come to represent. Based on previous experience as well as psychological insights, we propose the use of a game in crowdsourcing scenarios in order to attract and retain a larger share of entertainment seekers to relevance assessment tasks.
A joint proposal with Christopher Harris and Padmini Srinivasan from The University of Iowa as well as Arjen de Vries from CWI Amsterdam was awarded a Crowdsourcing Challenge research grant.
